Ubuntu 17.10 expo and genymotion errors and solutions

Switched to a LAN URL because the tunnel appears to be down. Only devices in the same network can access the app. You can restart the project to try reconnecting.

Solution:

Due to some bug you must start xde (expo development environment) before genymotion. Also i needed to run xde from root user login. (not su or sudo ).
UPDATE: The following problem of adb version fixed this problem too.
